Abstract (original English)
The extracellular matrix (ECM) is the natural scaffold of all soft tissues in tissue engineering. Of special interest is the use of ECM as a hydrogel, which can be used to enclose cells and to be molded into any form by 3D bioprinting. Protocols for the preparation of ECM vary in the use of physical and chemical processing steps, the use of different detergents for decellularization, and the removal of DNA and RNA residues and show a different use of solvents and wash buffers. We have, therefore, compared seven different variations for the decellularization of a primary porcine isolate to manufacture decellularized adipose tissue (DAT) for their use in adipose tissue engineering and as a hydrogel in particular. Decellularization efficacy was assessed by DNA quantification while retention of ECM components was evaluated by measuring the content of hydroxyproline and glycosaminoglycan (GAGs). Depending on the decellularization protocol, the composition and DNA content of the resulting DAT were different. All DAT samples were processed into hydrogels to assess their mechanical properties as well as their influence on cellular metabolic activity and cell differentiation. The different compositions of the DAT and the resulting hydrogels had an effect on the stability and printability of the gels. Some DAT that were digested with hydrochloric acid (HCl) were more stable than those th
